Recent graduate student Priyanka Chaudhari was interviewed about her research on the genetics of RoundUp resistance in hairy fleabane by California Ag Today: check it out here.
Two recent students (Alex Lopez and Josue Duque) presenting their research at the International Weed Genomics Consortium 2021 annual meeting in Kansas City!
Investigation of the recent California agricultural invasions of Palmer amaranth and waterhemp:
The most agriculturally problematic species in the weedy plant genus Amaranthus are A. palmeri (Palmer amaranth) and A. tuberculatus (waterhemp), which have both rapidly evolved resistance to a variety of different chemical classes of herbicides. Palmer amaranth is native to the Southwestern U.S., and waterhemp is native to the eastern U.S., and both have recently started becoming common invaders in Central Valley agroecosystems. Read more…

Population genetics and species delimitation in the native California genus Fritillaria:
We are interested in California species of the northern temperate genus Fritillaria (which have the largest known genomes in angiosperms, with up to 83 Gb of DNA) because two species, F. atropurpurea and F. pinetorum, are very difficult to distinguish using morphology alone in the southern Sierras. We are experimenting with genomic methods to further investigate species delimitation, population genetics, and phylogenetics in this group. Read more…
